Highlights

CO₂ - TRANSCRITICAL HEAVY DUTY SERIES

Frascold’s transcritical Heavy Duty reciprocating compressors are designed to be used with CO₂ natural refrigerants and offer the perfect solution for the commercial, industrial, transport, process cooling, and heat pump sectors. The models in this series are suitable for single-phase or integrated, booster and cascade systems and have been designed to withstand high plant downtime pressure. This helps provide ease of maintenance and a more efficient, less taxing start-up.

The particularly strong construction of the compressors allows them to operate with high operating delivery pressures of 140 bar(a) and a maximum plant downtime pressure (PSS) of 80 bar(a). Please note: models in the D and Z series operate with a delivery pressure of 100 bar(a).

This series has been developed in our state-of-the-art design and manufacturing facilities utilizing the most cutting-edge technologies available. The end result is extremely high-performing and safe units that can be depended on to get the job done.

Features

Advantages

Better Operating Range

This series of CO₂ transcritical Heavy Duty reciprocating compressors is convenient to use in a wide range of applications, providing a durable, safe, and efficient solution for operations in transcritical processes.

Higher Degree of Safety

The use of CO₂ natural refrigerants creates enhanced safety features and ultimate reliability in one package. Non-flammable and chemically inert at low concentrations, they feature a very low GWP and lower air emissions to help lessen environmental impact.

Lower Oil Carryover

Frascold transcritical Heavy Duty reciprocating compressors are designed to provide low oil carryover, minimizing the chance for leaks and providing higher degrees of protection and lubrication for all integral moving parts. This provides an optimal, high-quality operation, which ensures maximum efficiency and that the highest performance levels possible are consistently met.

High Standstill Pressure (PSS)

The high standstill pressure (PSS) of all the transcritical Heavy Duty reciprocating compressors in the CO₂ series allows the correct management of plant downtime pressure, making maintenance easier and providing a quick start-up without having to use active or passive systems.

Compact and Quiet Design

Frascold transcritical Heavy Duty reciprocating compressors are unique in their relatively light design, space-saving dimensions, and overall quietness. These features allow these units to be used in many different applications, especially within smaller systems where space may be at a premium.

CapaFlex TM mechanical regulation

The CapaFlex^TM capacity control system is exclusively available on Frascold compressors for transcritical applications. This advanced technology helps regulate the flow rate transfer of CO2 refrigerants through suction inlets. The alternating periods of opening and closing of the suction inlets allow proper partialisation of the compressor, providing for more optimal loads and preventing on-off cycles as much as possible.

Frascold - CO2 Industrial system in Australia

The first full transcritical CO2 industrial refrigeration system by Frascold is presented in Australia

Frascold contributed to the creation of the first full transcritical CO2 refrigeration system for industrial applications in Australia. Using Frascold compressors at the core of a wider installation, this project involved a local wholesaler in New South Wales. The project included the construction of a wing for the presentation and storage of fresh and frozen products, a meat processing area, a dedicated entrance for sales, and a loading-unloading area.
